  • the rolling bearing is of the type comprising an outer element and an inner element, between which is provided at least one row of rolling elements. One of these elements remains fixed relative to one frame, while the other can be rotated by the control wheel.
  • the instrumented bearing comprises means for detecting the rotation parameters of the rotating element, so as to control an electric or electro-hydraulic actuator.
  • the steering wheel actuated in rotation by the driver, is mounted on a fixed support by means of one or two rolling bearings to which is added a rotation detection system, integrated or not with the rolling bearings.
  • This detection system delivers a signal representative of the rotation of the steering wheel (angle, direction and angular velocity) which is conveyed to a signal processing system, then to an electronic control logic system which in turn sends appropriate signals to electrical or electro-hydraulic actuators which cause the orientation of the vehicle wheels according to the orders given by the driver.

Moreover, nothing is provided for an integrated and reliable processing of the signal emitted by the sensor.
